The caries experience of 123 fluoride users (F-tablets and/or F-toothpaste) was compared with that of a group of 226 non-users. Fluoride users appeared to have a 15% lower DFS score (16.2) than non-users (19.0). After a matching procedure had been used to correct for some intervening variables (socioeconomic status, toothbrushing habit, sweet consumption) no difference was found between the groups of F-tablet and F-toothpaste users and the respective groups of matched non-users. The difference in caries experience of 15% between users and non-users remained in only one group after the matching procedure, that in which the children used both F-tablets and F-toothpaste.
将123名使用氟化物（氟片和/或含氟牙膏）的人群的龋齿情况与226名未使用者进行了比较。使用氟化物的人群的DFS评分（16.2）似乎比未使用者（19.0）低15%。在采用匹配程序校正了一些干预变量（社会经济地位、刷牙习惯、甜食摄入量）后，氟片使用者组和含氟牙膏使用者组与各自匹配的未使用者组之间未发现差异。匹配程序后，使用者和未使用者之间15%的龋齿情况差异仅在一组中仍然存在，即儿童同时使用氟片和含氟牙膏的那组。
